However, the solder paste pattern emitted by pcb does not care for the solder mask. The solder paste always covers the entire pad. For masks smaller than than the pad dimensions this results in solder paste on top of solder mask. This is clearly not useful and results in complains by the fab.

Suggestion: Adjust solder paste size to solder mask dimensions if these are smaller than the pad.

Hi Ineiev,
For modern systems it is not required. I am in the habit of adding
the "L" suffix as defensive programming - some very old compilers
treat constants as 16 bit unless you add the "L". Probably these
compilers aren't used any more :) From memory it was the Gaio
compiler for the H8 microcontroller, or similar. I don't think that
PCB will be ported to H8 any time soon ;-), so feel free to remove the
"L".
Best regards,
Stephen
